Introduction
1 Introduction
1.1 Instrument description
The 795 KFT Titrino is a fast and precise Titrator for the water determination according to
Karl Fischer. The 795 KFT Titrino is equipped with a LCD graphical display on which titration curves can be observed in real-time.
Ready-to-start methods for the most common applications are stored in the internal
method memory. The operator is free to modify and overwrite this methods or to create
and store his own titration sequences.
Data exchange with a PC is possible with the Metrodata VESUV Software and with Metrodata TiNet Software complete remote control, data acquisition and evaluation via PC is
enabled.

Minimum volume increment (0.1...9.9 µL, min.)
<CLEAR> sets "min.".
This parameter determines the addition rate at the start
and the end of the titration, see also page 21.
This parameter influences the titration speed and
therefore its accuracy very strongly: A smaller
"min.volume incr." results in a slower titration.
Type of stop criteria (drift, time)
Titration stops, if EP and stop drift are reached
(1...999 µL/min)
Titration stops if there is no dosing during t(delay)
(0...999 s, INF)
<CLEAR> sets "INF".
Switch off when EP is reached and the set time after
the last dosing has elapsed.
If t(delay) is "INF"
Stop after a time (0...999999 s, OFF)
<CLEAR> sets "OFF".
Stop after the set time after start of titration. "OFF"
means no stop, i.e. titration for an "infinitely" long time.

Control parameters for KFT
The control parameters can be set according to your samples. The default parameters
are already set to get satisfactory results. Optimize the control parameters for specific
samples only.
During the titration, reagent dosing is carried out in 3 phases:

performed in single steps.
The last dosing steps are

• The position and curve characteristics of the line between the ranges of excess water
or excess iodine depends on the type of sample and the ingredients of the working
media.
• The endpoint has to be set close to the range margin, but always within the iodine
excess range. If the endpoint is set too close to the limit, an overdose of KF reagent
may be dispensed. The steeper the curve at the preset polarization current I(pol), the
more delicate it is to titrate to a steady and reproducible endpoint. For the titration of
troublesome samples, the particular conditions must be optimized by trial and error.
Always mind the color of the working medium at the end point as your guideline.
Remark: In most cases the preset default parameters provide precise and
reproducible results.
• If you select negative values for a parameter, you should choose negative values for all
other parameters too in order to have compatible parameter sets.
• In KFT Upol mode, all parameters work in a similar manner as in KFT Ipol mode.

795 KFT Titrino
The determination of the free water is easily done, as far as the specifications of the
reagent manufacturer regarding the "water capacity" of the reagents are considered.
Problems may occur with specific sample matrices. The relevant literature contains many
precise analysis instructions. Here, we give you some useful hints for the sample addition.
Sample addition
For sample addition various accessories are available, for example injection syringes,
weighing spoons etc.
It is a good idea to apply the back-weighing technique, except when you are disposing
small amounts of liquids with a micro-syringe. Fill the syringe or the weighing spoon with
your sample just before the titration (e.g. during conditioning) and tare it on a balance
with an appropriate precision, which ideally is connected to the Titrino. Sample size
request should always be switched on (see page 19). Add the sample during the request
for the sample size, and weigh the syringe or weighing spoon again to evaluate the
weight difference. Use the transfer of balance data to enter the correct sample size if
possible. The weight has to be transmitted in gram. If you transfer the sample size from
the balance, the sample size request is confirmed automatically, and the titration is
started at once. Otherwise use the keypad to enter the weight.
If the sample size request is switched off, and preconditioning is set, you are explicitly
prompted to add your sample. For six seconds, the message "add sample" is displayed
after which the titration is started by the Titrino itself. This waiting time can be extended by
pressing <MEAS/HOLD>.
Solid samples
Use the glass weighing spoon 6.2412.000 and dispose the sample through the opening
for the septum stopper.
Liquid samples
Use a disposable syringe (2...20 mL) or a micro-syringe with a long needle attached.
Puncture the septum and dispose the sample carefully. When using disposable syringes,
add the liquid sample carefully without dipping into the solvent. Draw back the last drop
of sample into the syringe before you redraw the needle. For disposing an exact, small
volume of liquid sample, use a micro-syringe. Proceed as described above, but dip the
needle into the preconditioned solvent and dispose the sample carefully. Here drawing
back of solvent or sample adhering to the needle is not recommended.
Always keep in mind to exchange the septum as soon as it shows any large punctures
impairing the tightness of the titration cell.
Pasty, viscous samples
For samples which cannot be disposed with a needle because of their high viscosity, you
can handle your samples with disposable syringes with a large volume without using a
needle. Dispose your sample through the opening of the septum stopper. Back-weigh the
syringe after addition of the sample. Be sure to wipe off any adhering excess sample
substance of the syringe before taring it.
In any case, pay attention to prevent the penetration of atmospheric moisture into the
titration vessel when you are disposing the sample. If you still have to open the titration
cell for any reason, determine a blank value and take it into account for the calculation of
the titration result (see page 132).

side:
What to do if ...
Problem
Dosing at end too long and
increments too small. "Is never

Possible causes and remedial action
• Increase "min.volume incr.".
• Change stop criterion. Try to increase stop drift or
use a short stopping time as stop criterion, e.g.
• For problematic samples change solvents with
ketones or aldehydes in 2-methoxyethanol or with
amines mixture in methanol/glacial acetic, e.g., see
literature.

• Does your sample evolve water extremely sluggishly?
Work with the KF oven.
• Are acids esterified in your sample? Change solution
more frequently. Increase buffer capacity of the
solvent.
• Does your sample contain ketones or aldehydes?
Use special reagents suitable for ketones and
aldehydes.
The endpoint is reached "too
rapidly".
• Reduce "max.rate".
The titration times become
longer and longer.
• With 2-component reagents the buffer capacity of the
solvent can be exhausted. Change solution.

method memory, the status of the statistics calculation is retained.
3) Change the number of the individual values n under "mean n", if necessary.
4) Perform at least 2 titrations. The statistics calculation are constantly updated and
printed. The values are printed in the short and full result report.
5) The statistics report can be printed with <PRINT><STATISTICS><ENTER>.
Rules:
• Recalculated results are incorporated in the statistics calculation.
• If a result of a particular titration can not be calculated, no results for this determination
are incorporated in the statistics calculation. However, the sample counter is still
operative, i.e. the statistics calculation start afresh when the number of required
individual determinations has been performed.
• If the statistics are switched off ("statistics" LED no longer on), results are no longer
entered in the statistics table. But the table remains unchanged. When the statistics
are switched on again, you can immediately continue working.
• If you delete results, all results of the determination with index n are removed from the
statistics evaluation.
• On method change, the old statistics table is cleared and the statistics instructions of
the new method are followed.
• Old results in the statistics table can be deleted with "delete all" (<PARAM>,

2.14 Silo memory for sample data
In the silo memory or pushup storage, sample data (method, identifications and sample
size) can be stored. This is useful, e.g. when you work with Sample Changers and other
automatic sample addition systems or if you wish an overview of your determination
results, see page 41.
SILO
9
Press the key <SILO> for working with the silo
memory. The status LED "silo" is on when the silo
memory is switched on. The silo memory works by the
FIFO principle (First In, First Out).
-
If the silo memory is switched on, sample data are routed to the last free line of the silo
memory. If no new value is put in, the value from the last line is automatically copied. In
this manner, data can be simply taken over when they remain unchanged.
When the instrument is started, the sample data are fetched from the next silo line.

1 silo line needs between 18 and 120 bytes memory capacity.
Filling the silo memory with a connected balance
If the silo memory is filled from the balance, you must ensure that there is sufficient space
in the silo memory for the required number of silo lines! The number of free bytes is given
in the user memory report.
When the sample data are entered from a balance, the transfer of the sample size is
taken as the end of the silo line. You should not send data from the balance and edit the
silo memory at the same time.
For mixed operation, manual input of identifications and sample sizes from a balance, the
values from the balance are sent into the line in which editing just takes place. Confirmed
the data with <ENTER> at the Titrino.

3.1 General rules
3 Operation via RS232 Interface
3.1 General rules
The Titrino has an extensive remote control facility that allows full control of
the Titrino via the RS 232 interface, i.e. the Titrino can receive data from an
external controller or send data to an external controller. CR and LF are used
as terminators for the data transfer. The Titrino sends 2xCR and LF as termination of a data block, to differentiate between a data line which has CR and
LF as terminators. The controller terminates its commands with CR and LF. If
more than one command per line is sent by the controller, ";" is used as a
separator between the individual commands.
The data are grouped logically and easy to understand. Thus e.g., for the selection of the dialog language, the following must be sent
&Config.Aux.Language "english"
whereby it is sufficient to only transmit the boldface characters, thus:
&C.A.L "english"
The quantities of the commands above are:
Config
configuration data
Aux
auxiliaries, various data
Language
setting the dialog language
The data are hierarchically structured (tree form). The quantities that occur in
this tree are called objects in the following. The dialog language is an object
which can be called up with the
&Config.Aux.Language
command.
If one is in the desired location in the tree, the value of the object can be queried.
&Config.Aux.Language $Q Q means Query
The query command $Q initiates the issuing of the value on the instrument
and the value emission is triggered. Entries which start with $, trigger something. They are thus called triggers.
Values of objects can not only be queried, they can also be modified. Values
are always entered in quotes, for example:
&Config.Aux.Language "english"

Rules
Example
The root of the tree is designated by &.
The branches (levels) of a tree are marked with
a dot (.) when calling up an object.
When calling up an object, it is sufficient to give
only as many letters as necessary to uniquely
assign the object. If the call is not unequivocal,
the first object in the series will be recognized.
Calling up the dialog language
Upper- or lowercase letters may be used.
&C.A.L or &c.a.l
To an object a value can be assigned. Values
are signified at the beginning and end by quotes
("). They may contain up to 24 ASCII characters.
Numerical values can contain up to 6 digits, a
negative sign, and a decimal point. Numbers
with more than 6 characters are not accepted;
more than 4 decimal places are rounded off. For
numbers <1, it is necessary to enter leading
zeros.
Entering the dialog language:
&C.A.L"english"
The current object remains until a new object is
called.

3.1.3 Status messages
In order to have an efficient control by an external control device, it must also
be possible to query status conditions; they provide information on the status
of the Titrino. The trigger $D initiates output of the status. Status messages
consist of the global status, the detailed status and eventual error messages,
e.g. $S.Mode.KFT;E26. The global status informs on the activity of the process, while the detailed status conditions show the exact activity within the
process.
$G
$H
$C
$R
$S
Go:
Hold:
Continue:
Ready:
Stop:
The following global status conditions are possible:
The Titrino is executing the last command.
The Titrino has been held ($H, key <meas/hold> or by an error which effects
the hold status).
The Titrino has been restarted actively after hold.
The Titrino has executed the last command and is ready.
A process has been aborted in an "unnatural manner". e.g. stopped or aborted
because there was an error.
Detailed status conditions
Status conditions of the global $G:

Status conditions of the global $H:
The status message of the action which has been held appears.
If the process is held because a monitored limit has been violated, its status
message is $H.Mode.KFT.Titr.
Status conditions of the global $C:
The status conditions of the global $C are identical with the ones of the global
status $G. They appear when the process has been restarted actively from the
status "Hold" ($C, key <meas/hold> or automatically after elimination of an
error).
Status conditions of the global $R:
Quick manual measurement from the initial status in mode KFT.
$R .Mode.KFT .Inac:
Instrument in the KFT mode, inactive.
.Cond.Ok:
Instrument in the KFT mode, conditioning, endpoint reached.
.Cond.Prog: Instrument in the KFT mode, conditioning, endpoint not reached.
$R .Assembly.Bur.ModeDis: Buret in the DIS mode, inactive.
$R .Mode.KFT.QuickMeas:

Status conditions of the global $S:
$S .Mode.KFT.QuickMeas:
Quick manual measurement from the initial status in mode KFT.
The instrument gives the status from which it has been stopped. The detailed
status information is therefore identical the information for the global status

3.3 Properties of the RS 232 Interface
Data Transfer Protocol
The Titrino is configured as DTE (Data Terminal Equipment).
The RS 232 interface has the following technical specifications:
• Data interface according to the RS 232C standard, adjustable transfer parameters, see pages 11 and 75.
• Max. line length:
512 characters
• Control characters:
CR (ASCII DEC 13)
LF (ASCII DEC 10)
XON (ASCII DEC 17)
XOFF (ASCII DEC 19)
• Cable length:
max. approx. 15 m
Start
7 or 8 Data Bit
Parity Bit
1 or 2 Stop Bit
Only a shielded data cable (for example, METROHM D.104.0201) may be
used to couple the Titrino with foreign devices. The cable shield must be
properly grounded on both instruments (pay attention to current loops; always
ground in a star-head formation). Only plugs with sufficient shielding may be
used (for example, METROHM K.210.0381 with K.210.9045).
3.3.1 Handshake
Software-Handshake, SWchar
Handshake inputs on the Titrino (CTS) are not checked.
Handshake outputs (DTR, RTS) are set by the Titrino.
The Titrino sends XOFF when its input buffer contains 384 characters. After
this it can receive 128 extra characters (including LF).

3.3.3 What can you do if the data transfer does not work?
Problem
Questions for remedial action
No characters can be received on a connected printer.
-
Are the instruments switched on and cables plugged in
correctly?
Is the printer set to ”on-line”?
Are baud rate, data bit and parity the same on both
instruments?
- Is the handshake set properly?
If everything seems to be ok, try to print a report with the key
sequence <PRINT><SMPL DATA><ENTER>. If this report
is printed out correctly, check if reports are defined in key
<DEF>.
No data transmission and the
display of the Titrino shows an
error message.
-
error 42: Transmission error. Is the printer set to "on-line"?
Is the connection cable properly wired?
error 43: Data output of the Titrino disabled for longer than 6
s by XOFF.
error 36-39: Receive error. Are the RS settings the same on
both devices?
The received characters are
garbled.
-
Wrong line spacing.
The printer does not emulate completely the preset mode.
Usually these problems arise with the IBM mode. Set the printer
to a different mode (e.g. Epson).
Printout of titration curve is not
ok. Other reports are printed ok.
Handshake is necessary for the printout of curves.
- Is your cable correctly wired? (The DTR of the printer has to
be connected to the CTS of the Titrino.)
- Set "HWs" for the handshake of the Titrino. Configure the
printer such that its DTR is set (possibly with DIP switches).
795 KFT Titrino
Are the RS settings the same on both devices?
Has the correct printer been selected?
Data transfer has been interrupted on the hardware side
during the printout of a curve. Re-establish connections and
switch printer off/on.

4.2 Diagnosis
4.2 Diagnosis
4.2.1 General
The 795 KFT Titrino is a very precise and reliable instrument. Thanks to its rugged construction it is virtually impossible for external mechanical or electrical influences to have
an adverse effect on its functions.
Although the occasional fault in the instrument can not be excluded completely, it is certainly much more likely that malfunctions are caused by wrong operation or handling or
through improper connections and operation with non-Metrohm instruments.
It is advisable in each case to isolate the fault with the rapid and easy to perform diagnostic tests. The customer thus need not call METROHM service until there is a true fault in
the instrument. In addition, with the aid of the numbering in the diagnostic program he
can provide the service engineer with much more accurate information.
In inquiries always quote the manufacturing (page 5) and program number (see configuration,
page 11) and specify possible error displays.
4.2.2 Procedure
• The diagnostic steps must be performed in sequence and compared with the reactions of the 795 KFT Titrino (indented). In the "yes" case, continue with the next instruction.
• If the instrument does not show the expected reaction ("no" case), the appropriate
diagnostic step must be repeated to exclude an operating error. With repeated
wrong reactions, however, there is a strong possibility that a malfunction exists.
• The diagnostic steps allow re-entry into the test routine for repetition if the following
display appears:
diagnose press key 0...9
If the instrument is in a subprogram of the diagnostic routine: Press <CLEAR>.
If need be, switch the power off then on again after a few seconds. At the same time press key <9>
until the above display appears.
• If <CLEAR> has been pressed during the display of 'diagnose press key
0...9', the instrument returns to the user program.
• Error display: An error is shown in the display as follows:
error XX
error number
• If a fault causes the buret drive to stick at the top or bottom end of the cylinder, see
page 111, point 4.4.

• Measure spindle lifting (can be performed only if the 3.496.0070 Dummy Exchange
Unit is inserted or the locking switch (in right hole) is carefully operated with a
screwdriver after removal of the Exchange Unit).
From the start point, the spindle travels 80 mm. Instead of the spindle height, the expelled

The following generally holds: Spindle and stopcock must move at a constant speed
(noise!). In the filling setting, the stopcock coupling must position the lever of the Exchange
Unit correctly at the left stop (with virtually no play and without sticking).
• Set potentiometer 'dV/dt' to left stop.
• Press <DOS> (on instrument) at same time and use a stopwatch to measure the

On the odd occasion large disturbing signals (e.g. mains spikes, lightning, etc.) can have
an adverse effect on the processor functions and hence lead to a system crash. After
such a crash the RAM area must be initialized. Although the basic instrument data remain
stored, the RAM initialization should be performed only when necessary since the stored
user data (configuration, parameters, calculation variables, etc.) are cleared as a result.

If 'system error 3' appears in the display, <CLEAR> can be used to return to the instrument program. The initialization values are loaded automatically. The instrument thus
remains capable of measurement. However, possibly a small loss in accuracy must be
anticipated. A new optimum adjustment can be performed by Metrohm service. The error
message 'system error 3' always appears after the instrument is switched on until this
adjustment has been performed.

• Disconnect instrument from power supply!
• Remove control knob.
• Place instrument over edge of bench to allow the M3 screws to be removed (Fig. 7).
• Remove M4 screws.
• Lift off top part of instrument together with Exchange Unit in the manner shown by
the arrow.
The electronic circuits are now accessible!

5.1 Setting up and connecting the instruments
5 Preparations
The mains cables supplied with the instrument are three-core and
equipped with a plug with an earthing pin. If a different plug has to
be fitted, the yellow/green lead must be connected to the protective
earth. Each break in the earthing inside or outside the instrument
can make it a hazard.
When the instrument is opened or if parts of it are removed, certain
components may be live if the instrument is connected to the mains.
The mains cable must therefore always be unplugged when certain
adjustments are made or parts replaced.
When peripheral instruments are connected to the KFT Titrino, the Titrino and the instruments to be connected have to be switched off,
otherwise all instruments could suffer damage!
Before connecting a printer or a balance to the RS232 Interface,
switch off the Titrino!

below, ensure that the Epson mode is emulated or that it uses the international character set following the IBM Standard Table 437 and
IBM-compatible graphics control characters.
If a balance is connected at the same COM of the Titrino as a
printer, you need the 6.2125.010 + 6.2125.030 Adapters.

The balance type must be preselected at the Titrino with the
<CONFIG> key.
The weight is transferred as a number with up to 6 digits, sign and
decimal point. Units and control characters sent by the balance are
not transmitted.
With the aid of a special input unit supplied by the balance manufacturer, in addition to the weight identifications and methods can be
114
795 KFT Titrino
inputted from the balance. For this, the address of the identifications
and method, resp. must be preselected on the input unit.

If balance and printer are connected at the same Titrino COM you
need the 6.2125.010 and 6.2125.030 Adapters.
If the balance works only with 7 bit and the printer with 8 bit and if
they are at the same Titrino COM, the balance has to bet to "space
parity" and Titrino/printer to 8 bit, "no parity".
5.1.4 Connection of a KF Oven
It is expedient to place the oven on 6.2041.180 instrument bridge.
Take care that the gas outlet of the oven enters the titration vessel as
directly as is possible to prevent the formation of condensed water in
the outlet tubing.
Oven on 6.2041.180
instrument bridge
Connection of both RS interfaces (cable 6.2125.110) is only necessary when you require the oven results in the 795 Titrino report. Make
sure there is no report output from the oven!

When the RS interfaces are not connected then the following setting
must be made at the Titrino: <PARAM>, >preselections, "Oven:
no".
If you enter one of the COMs of the Titrino for this parameter then
your Titrino result report will contain the oven data "heating time",
"sample temp.", "lowest temp.", "highest temp." and "gas flow". The
start is triggered at the oven. When the Titrtrino titration vessel has
been conditioned the oven automatically starts the titration.
The 707 KF Oven can also be connected instead of the 768 KF
Oven.

With 6.2141.030 cable (instead of 6.2141.020), two Titrinos can be
connected to the 730 (or 760) Sample Changer at the same time.
• The "Remote" socket allows not only connection of a sample
changer but also additional control functions. Pin assignment of
the "Remote" socket and control possibilities, see page 125.
• If a calibration has to be performed with the sample changer, the
calibration parameter "sample changer:" must be set to "ON".
• In connections with the sample changer, "auto start" should be
set to "OFF" in the <CONFIG> key. The start command is given
by the Sample Changer.

5.1.6 Connection of the 774 Oven Sample Processor
The Oven Sample Processor heats the sample and transfers the
moisture from the sample to the titration vessel of the Titino. Titrino
and Oven Sample Processor are connected via the remote sockets
(cable 6.2141.020) as well as via the RS interfaces (cable

5.1.8 Connection of a Remote Box
A barcode reader and/or a PC keyboard can be connected to 6.2148.000 Remote Box.
The barcode reader and PC keyboard are used as input aids.
Only plug in and unplug the Remote Box when the Titrino is switched off! The Remote
Box is screwed onto the "Remote" socket of the Titrino. The remote lines of the Titrino are
then accessible at the "Remote" socket of the Remote Box.
5.1.8.1 Connecting a barcode reader
Barcode readers with a 5-pole DIN plug can be connected to 6.2148.000 Remote Box. A
precondition is that the barcode reader can emulate a PC keyboard. If a barcode reader
and a PC keyboard are to be connected at the same time then the barcode reader must
have a T-connection plug. The PC keyboard will then be plugged into this barcode reader
connection.

The barcode string goes to the entry field in which the cursor is currently located.
If the silo memory is switched on the barcode string always goes to the
method. The cursor position has no effect.
If the silo memory is switched off the input has no meaning.
The barcode string always goes to Id1. The cursor position has no effect.
As for id1.
The barcode string always goes to the sample size. The cursor position has no
effect. If the silo memory is switched on the silo line will be concluded with the
sample size and the cursor moves to the next silo line.
Settings at the barcode reader:
Plug the barcode reader into the Remote Box. The barcode reader instruction manual
contains the codes which you must enter.
1. Bring the barcode reader into the programming mode.
2. Make the necessary setting for emulating a PC keyboard (may be country-specific).
Select <ENTER> or "CR + LF" as termination sign.
3. Exit the programming mode.
Notes:
• If longer characters chains than are permitted by the corresponding input are transmitted then the first n characters will be accepted; the last characters will be cut off.
• If the silo memory is switched on and the settings "barcode: method" or "barcode: idX"
are operative, the first silo line will be created when the string is received. Higher silo
lines than 1 are only created and concluded with the sample size.
5.1.8.2 Connecting a PC keyboard
PC keyboards with a 5-pole DIN plug can be connected to 6.2148.000 Remote Box. For
keyboards with a PS/2 plug an adapter PS/2→DIN is available in PC shops.
Settings at the Titrino:
Under key <CONFIG>, >peripheral units, "Remote Box: on"
Keyboard:
Select the country-specific keyboard layout of your PC keyboard.
If the Titrino does not support your keyboard you should select a keyboard which has the
closest possible layout (for example check the 2nd occupancy of the numerical keys).
Country-specific special characters will probably not be converted correctly.

6.3.7 KF titrations with various KF reagents
If you work parallel with different KF reagents, you can use different methods for each KF
reagent. The titer determination is performed with H2O or methanol standard as described
for the method "H2OTiter". The factor C01 has to be adapted to the standard used (see
page 130). For each reagent, the titer is assigned to another common variable which is
taken into account in the calculations of the titration method (see table). The titration parameters are suitable both for water determinations using one-component reagents and
two-component reagents. The KF titations without blank value subtraction are executed
according to the description for the method "KF" (see page 135). For the blank determination the method "Blank_KF" is used. The mean value of three blank determinations is assigned to the common variable C38. The KF titations with blank value subtraction are
executed according to the description for the method "KF-Blank " (see page 133). Remember that you need to adapt the factors in the formula (see table on page 134).

Determination of the bromine number in petroleum hydrocarbons according to ASTM D
1159-84.
The bromine number is defined as the quantity of bromine in mg which reacts with 100 g
of the sample.
Electrode:
input "Pol".
Titrating agent:
Bromide/bromate-solution,
c(BrO3–/Br–) = 0.5 mol/L
Dissolve 51.0 g KBr and 13.92 g KBrO3 each
in distilled water and add up to 1 L.
Solvent:
714 mL glacial acetic acid,
134 mL 1,1,1-trichlorethane,
134 mL methanol,
18 mL w(H2SO4) = 0.2 (20%)
Sample:
Pipet 25 mL 1,1,1-Trichloroethane into a
50-mL volumetric flask and add the sample
(see table below). The weight of the sample is
obtained by difference between the weight of
the flask before and after addition of the sample. Fill the flask to the mark with
1,1,1-trichloroethane and mix well.
Add 5 mL of the sample solution to 110 mL
solvent in the titration vessel and mix.
The blank sample is titrated in the same way.
– Result in % (g bromine/100 g sample)
– Consumption of Blank sample in mL
– Normality of the titrating agent in mol/L
– Molecular mass of Br (79.9 g/mol) ∗ 0.1
(Conversion to % in weight and L)
– C04 = Dilution factor (Has to be calculated ac
cording to the sample preparation, for the
method described above, the factor is 10.)

6.4.2 Wet tests
GLP (Good Laboratory Practice) requires the periodic validation of the analytical instruments. The reproducibility and accuracy of the instruments are checked.
An annual repetition of the procedure appears to be sensible. Depending on the requirements a more frequent check may be indicated, e.g. every 3 or 6 months.
Guidelines for the testing regulations (SOP, Standard Operating Procedure) are given in
Metrohm Application Bulletin
No. 255: Validation of Metrohm KF Titrators and KF Oven according to GLP/ISO 9001.
The validation interval can be checked by the Titrino (set under <CONFIG>, monitoring).
If the interval has elapsed the Titrino displays the message validate instrument.
6.4.3 Maintenance and adjustment of the Titrino
The Titrino should be serviced and adjusted by Metrohm service at regular intervals.
The Titrino can check the date of the next service with the help of the monitoring function
"Service" under <CONFIG>, monitoring. If this date has been passed then the Titrino will
display the message service is due.
